All plants with chlorophyll utilise high frequency electromagnetic (e/m) radiation, in the form of light, as an essential part of their metabolism. (see).
Recent (2020) experiments with Arabidopsis thaliana - a commonly-used botanical research plant - have shown that plants appear to be able to utilise much lower frequency (e.g 7MHz) e/m radiation.
How living systems respond to weak electromagnetic fields represents one of the major unsolved challenges in sensory biology. Recent evidence has implicated cryptochrome, an evolutionarily conserved flavoprotein receptor, in magnetic field responses of organisms ranging from plants to migratory birds. However, whether cryptochromes fulfill the criteria to function as biological magnetosensors remains to be established.

There is currently no explanation of how the process works, or why it has evolved. The research team note that as well as the implications for possible growth enhancement techniques, it may also be possible to use plants to detect e/m fields.
